Pulp

Currently, Pulp waits 5 minutes after noticing that a worker has gone missing, and then cancels all the tasks that were in its queue. It would be nicer if Pulp would automatically reassign all of those tasks to other workers when a worker is shutdown. It would also be nice if the system didn't have to wait five minutes to do this.Deliverables:Register workers for the shutdown signal, and make a handler that queues a task to mark that worker as missingRework the missing worker task to reassign queues rather than cancel their tasks.Such queues get deleted when drained
